The 900 mm High-Speed Polyethylene Film Blowing Machine processes HDPE and LDPE resin into continuous tubular film through extrusion, air cooling, haul-off and winding. It serves plastic bag production and general packaging applications, including shopping bags, T-shirt bags and garbage bags. The 900 mm traction roller supports a film width range of 300–800 mm. Extrusion output, film thickness and resin grade determine the operating conditions required for each application. Customized configurations are available to match film specifications, winding requirements and factory electrical standards.
Key Advantages
Defined Production Range
The specified film width and thickness range helps establish whether the machine suits the intended product sizes. Confirming these requirements before ordering provides a clear basis for equipment selection.
Coordinated Processing
Extrusion, cooling, haul-off and winding operate as connected stages. Appropriate process settings help maintain bubble stability, film dimensions and consistent roll formation.
Application-Based Configuration
The extrusion system, die head and winding arrangement can be selected according to the target material and film specifications. This keeps the equipment configuration aligned with the intended production process.
Bag-Making Compatibility
Film width, thickness and roll dimensions can be matched to downstream bag-making requirements. Confirming these details helps establish a suitable production workflow.

Film Applications
Shopping and T-Shirt Bags
Film width, thickness and roll dimensions should match the finished bag size and bag-making process. Resin selection depends on the required film properties and intended use.
Garbage Bags
Garbage bag production requires suitable film dimensions and material distribution for the target bag size and application. The required thickness and resin grade should be confirmed before selecting the operating configuration.
General Packaging Film
Polyethylene film can be used for general packaging and protective wrapping. Material grade and thickness should reflect the required flexibility, handling properties and end-use conditions.
Industrial Packaging
Industrial packaging applications require film specifications suited to the packaged product and handling process. Confirm the required width, thickness and roll format before finalizing the machine configuration.
Production Configuration
Extrusion System
Screw diameter, screw design, drive power and temperature control affect resin processing and production output. These parameters should be matched to the intended material and target film specifications.
Die Head and Cooling
The die head must suit the selected resin and film width. Cooling capacity and airflow influence bubble stability and the conditions required for consistent film formation.
Haul-Off and Winding
Haul-off speed must be coordinated with extrusion output and film thickness. Winding settings should accommodate the required roll width, diameter and handling requirements.
Material Feeding and Control
Material feeding and process control options can be selected according to production requirements. The final equipment list should identify the included systems and available control functions.
Customization Options
Film Specifications
Provide the target film width, thickness and resin grade. These details establish the processing requirements for evaluating the standard configuration or a customized setup.
Winding Arrangement
Winding options can be discussed according to roll dimensions, handling methods and downstream equipment. Any automatic winding functions should be confirmed in the final specification.
Auxiliary Equipment
A rotary die head, quick screen changer, corona treatment unit, automatic loader or PLC-controlled weighing system can be considered where available and suitable for the application.
Electrical Requirements
Specify the required voltage, frequency and phase before production. The electrical configuration should match the installation site's power supply and be documented in the final technical specification.
Quality and Pre-Shipment Checks
Mechanical Inspection: Inspect the main assemblies, transmission components, fasteners and moving parts against the agreed machine configuration.
Electrical Inspection:Check motor operation, temperature controls, electrical connections and control functions according to the specified equipment.
Trial Operation: Conduct an operational check using an agreed test procedure. Where included in the acceptance plan, review film formation, haul-off operation and winding performance under the specified test conditions.
Documentation Review: Confirm the final specification sheet, electrical information, operating instructions and accessory list before shipment. Record any agreed inspection and acceptance requirements.
Installation and Production Planning
Installation Space
Allow room for the machine, film handling, roll removal and routine maintenance. Confirm the overall dimensions and installation height before preparing the production area.
Factory Utilities
Prepare the electrical supply and supporting utilities required by the selected configuration. Confirm rated power and connection requirements before installation.
Bag-Making Integration
Check the required film width, thickness and roll dimensions against the bag-making equipment. Confirming these specifications helps coordinate film production with downstream converting operations.
Start-Up Preparation
Prepare the specified resin, target film dimensions and operating procedures before commissioning. Include operator training and routine maintenance planning in the start-up schedule.
